What it does
This Airworthiness Directive (AD/J4100/1 Amdt 1) requires operators and owners of BAe Systems Jetstream 4100 series aeroplanes to check whether a set list of state-of-design ADs (United Kingdom CAA and one EASA AD) apply to their aeroplane, and if an applicable AD has not already been complied with, to carry out the actions mandated by that AD. The Directive sets two discrete obligations, expressed in the document as Requirement 1 and Requirement 2. Requirement 1 obliges the responsible person to "determine the applicability of the ADs issued by the Civil Aviation Authority of the United Kingdom - CAA(UK), listed in Table 1 or the AD issued by the European Aviation Safety Agency - EASA, listed in Table 2." Requirement 2 then directs that "If it is determined that an AD listed in Table 1 or 2 is applicable and has not been previously accomplished, perform the actions required by that AD." The Directive attaches the full lists as Table 1 (a long list of CAA(UK) ADs by number, effective date and title) and Table 2 (one EASA AD, 2007-0268, with title).
The Directive fixes a compliance window: "For Requirements 1 and 2 - Within 30 days after the effective date of this Directive or prior to the issue of a Certificate of Airworthiness, whichever occurs first." The amendment containing these instructions became effective on 20 February 2008; the original Directive became effective on 31 January 2008. The background statement explains CASA's purpose-language: these state-of-design ADs include "either one time actions for which the compliance date and/or period has passed or multiple inspection/actions until a terminating action has been applied," and CASA determined they "may be applicable to recently registered or imported Australian aircraft." The Amendment explicitly notes it extended the list of ADs (additional ADs from CAP 476) beyond the original issue.
